Hong Mei 120 Fold Camera

I bought my first ever camera Hong Mei 120 in 1983 for 42 RMB, while I was at my college in Chong Qing, China. it is all manual and makes very good photos. It is still in good working condition after almost 30 years. Last week I took it with me hiking in a GuangZhou nearby hill . The camera is lighttight, without leaks at all. However when I finished the roll and opened the back only to find the film rolled too loose on the take up spool. So I decided to let it be. It seems that my Hong Mei knows that I will show her off on the Lomography site, and she volenteered to offer some help....
